基于罗丹宁埋底界面修饰的钙钛矿太阳电池性能研究
Study on the performance of perovskite solar cells based on rhodanine buried interface modification
The buried interface of perovskite solar cells (PSC) suffers from high defect density and energy level barriers,which severely limit the photovoltaic performance and stability of devices.To address these issues,this study introduced rhodanine (RHO),a buried interface modification molecule with multifunctional sites,at the buried interface.The synergistic effects of RHO at the buried interface and its influence on energy loss and carrier loss in PSCs were systematically investigated.Results demonstrate that the incorporation of RHO effectively improves the film quality of both perovskite and electron transport layers,passivates interface defects,optimizes interfacial energy level alignment,significantly suppresses non-radiative recombination of interfacial carriers,and facilitates efficient electron extraction and transport at the interface.Ultimately,the RHO-modified PSCs achieved a power conversion efficiency (PCE) of 22.97%,while maintaining 85% of their initial efficiency after continuous aging for 1 000 hours.
